Columbo attends the wedding of his police officer nephew. While her husband takes a shower, the bride disappears from the bridal suite. The groom enlists Uncle Columbo's help in unraveling the case. Seems she has been kidnapped by a psychopath who intends to kill her once he consummates "their" marriage.

A photograph is the only clue for Columbo when two dead men and a seven year old mystery with $4 million dollars involved as well as an obnoxious insurance investigator come into play.
